Lady Gaga took the top spot by earning $80 million over just the past 12 months, despite the singer’s lucrative Born This Way Ball being cut short due to her hip injury. Her staggering social media presence (she has 38 million followers on Twitter alone) is also cited as a deciding factor in Gaga owning the No. 1 position. Her next album, ARTPOP, is loosely slated for a release at the end of this year.
